lines_out.txt: This file contains the input Line geometries that form the boundary of the counties in NH state, USA.

points_out.txt: This file contains input Point
geometries that are used to constrain the line simplification
process. Notice the relationship of each point to the input set of line
geometries. After simplification this relationship should be preserved.

lines_simple_out.txt: This file containes the
result of a valid simplification. The resulting file should only
contain the Line geometries as only these are changed as part of the
simplification process. The output file should be formatted the same
way as the input file using the same IDs for each simplified line
geometry.

training_data.png: This file shows two images:
one for the input set of lines with the constraining points and the
second image with the simplified lines along with the points.
